She told housemates that she'd been dating someone on the outside for just four weeks, but the mystery man was later unmasked as plasterer Aaron Lacey, with pals revealing that they had actually been going out for two months and that he'd already moved in with her.

But despite all that, Chad and Sarah are hoping to give it a go on the outside.

However, there's one thing Chad won't allow his girlfriend to do.

He told Rylan Clark-Neal on CBB's Bit On The Side that he felt like he'd known Sarah for "34 months".

"And Sarah's the same way, she only cares about what's going on between me and her, and I love that."

When asked how he thinks they'll fair on the outside world, Chad said: "I mean honestly in the real world it's 10 times easier because if we don't like someone, or if someone's saying something we can just go away."

"You know now the only thing I'm going to have to tell her is maybe don't look at the Instagram comments.

"Maybe stay away from the Instagram comments for a bit."

Chad said he had "no clue" that something would happen between him and Sarah, and that it just happened "naturally".
